Munster had been planning for the game to go ahead. The Irish province trained at UL and held their pre-match media conference earlier today.

They and organisers European Professional Club Rugby had expected to be informed about security arrangements tomorrow morning, but instead the game has been postponed.

EPCR called off all of the games due to be played in France last weekend, in which neither team will be involved and the game is likely to be played when those games are re-fixed. The most likely date is the last weekend in November.

“In light of to recent tragic events, Stade Francais don’t wish to complicate the situation for the public or complicate the work of the security forces and the government by organising a sporting event to bring together 15,000 people in the Stade Jean Bouin,” a club statement said. “The club has therefore decided to postpone the meeting.”

Commenting on the announcement, Munster Rugby CEO Garrett Fitzgerald added, "We fully understand the decision to postpone this weekend's game and would not wish to hinder the work of government and security forces in what has been, and continues to be a very trying time for all in Paris and France.

"Now our attention must switch to working with Stade Francais and EPCR in rescheduling the game for a time that is amenable to both sides."

More than 500 Munster fans had bought tickets through official channels, while more had sourced them through Stade’s website.

Speaking before the postponement was confirmed, Munster coach Anthony Foley said: “Everybody's fully aware of what went on, everybody was watching the news and it's hard to fathom.

“First and foremost it's hard to put your head in it and then you have a lot of sympathy and respect for the people of Paris in terms of what they were put through.

“The game is only a small thing in the greater scheme of things but as a group we've talked about it to the leadership group and from a sportsman's point of view I think it's important that we're all united in it.”
